This Robot Hummingbird Is Almost as Agile as the Real Thing

Purdue roboticists have built a bio-inspired micro air vehicle that flies much like a real hummingbird

Hummingbirds are some of the most nimble fliers on Earth. Their speed and agility are spectacular, driven by the complex muscles that control their wings. This is a difficult system for robots to emulate, and in general, the small winged robots that we’ve seen have relied on compromises in control in order to be able to use flapping wings for flight.

At Purdue University’s Bio-Robotics Lab, Xinyan Deng and her students are taking a very deliberately bio-inspired approach towards winged robotic flight that has resulted in one of the most capable robotic hummingbirds we’ve ever seen. It’s just about the same size and shape as the real thing, and the researchers hope it will be able to perform the same sorts of acrobatic maneuvers as an actual hummingbird. And more importantly, it’s robust enough that it can use its wings as sensors to navigate around obstacles, meaning that it has a shot at being useful outside of a lab.
